Basketball Equipment & Facilities

Basketball courts may look similar at first glance, but their dimensions can vary depending on the level of play, the organization governing the game, and even the location. Whether you’re shooting hoops at your local gym or watching a professional match, the size of the court, the height of the hoops, and the placement of lines can differ significantly.
